ABI-decodes function arguments according to the ABI Item's input types (inputs).

Imports

Named
import { AbiFunction } from 'ox'

Examples

import { AbiFunction } from 'ox'
 
const approve = AbiFunction.from('function approve(address, uint256)')
 
const data = AbiFunction.encodeData(
  approve,
  ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045', 69420n]
)
// '0x095ea7b3000000000000000000000000d8da6bf26964af9d7eed9e03e53415d37aa960450000000000000000000000000000000000000000000000000000000000010f2c'
 
const input = AbiFunction.decodeData(approve, data)

ABI-shorthand

You can also specify an entire ABI object and a function name as parameters to AbiFunction.decodeData:

import { Abi, AbiFunction } from 'ox'
 
const abi = Abi.from([...])
const data = '0x...
 
const input = AbiFunction.decodeData(
  abi,
  'approve',
  data
)
